FC Magnesium carbon whole tapping hole

Work method :

The whole tapping hole in the use of steel mills, instead of split tapping hole has become a trend. Relative to the molding machines with friction by 250-300mm long sleeves made of bricks assembled steel

mouth, improving as the result of its unilateral axial compression uneven density, graphite trend in one direc-tion, as well as brick sleeve seams weak links vulnerable to molten steel caused by erosion,

intolerance washed shortcomings. While improving due to split up seam permeability steel tapping hole

when the demolition of the shortcomings of inconvenient operation.

Manufacture:

1.Use the high quality fused magnesia and high purity flake graphite phosphorus as the main raw material,

2.Add many kinds of additives and binding materials

3.Forming by Isostatic press

Product feature:

1. Excellent resistance of oxidation ,slag and spalling ;

2. Perfect thermal shock stability, high refractoriness;

3.Wonderful sinter ability, and adhesion.

Product application: apply to the steel parts out for BOF and electric arc furnace
